Help!!! Was it a love bite and why didn't he say anything?

My ex and I have been hanging out a lot lately. Last time I was at his place he kinda bite me or more so nibbled on me while we were kissing. I Teased Him and said "what is that a love bite" and he didn't say anything but continued as he was. Now I'm wondering if it was a love bite and if so why didn't he say anything when I asked him?
